Pancreaticoduodenal artery aneurysms (PDA) are rare visceral aneurysms. Celiac trunk stenosis represents a common attributable aetiology for those aneurysms. Therefore, an alternative treatment approach, which differs from those isolated aneurysms, is recommended. We hereby present a 77-year-old male patient who was admitted with sudden onset of severe abdominal pain and significant drop in haemoglobin, occurring within a 24-hour interval. Contrast-enhanced computed tomography revealed a ruptured visceral aneurysm arising from the anterior branch of the inferior pancreaticoduodenal artery...

Cutaneous leishmaniasis typically presents as a painless papule progressing to an ulcer or plaque. In this case study of the ear, the disease manifested as a small painful bump progressing into redness and swelling about the ear with purulent drainage. After multiple oral/intravenous antipseudomonal, antistaphylococcal, and antifungal treatments, there was no improvement. The skin progressed to an erythematous plaque and hemorrhagic ulcer; punch biopsy and speciation revealed Leishmaniasis guyanensis. The patient was switched to a seven-dose course of intravenous L-amphotericin B (visceral leishmaniasis protocol)...

Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD) are related gastrointestinal disorders characterized by abdominal pain associated with colonic hypersensitivity (CHS). Studies in humans have reported an abnormal colonization of Adherent-Invasive E. coli (AIEC) in the ileum of Crohn's disease (CD) patients associated with overexpression of the bacterial colonizing receptor CEACAM6. The aim of the present study was to investigate whether AIEC reference strain LF82 could induce intestinal impairment during infectious and/or post-infectious periods and subsequently the development of CHS...

Visceral artery aneurysms (VAAs) are a rare entity. Within this subset of aneurysms, gastroduodenal artery (GDA) aneurysms represent an even more rare occurrence. We present a case report of treating GDA aneurysm on semi-elective basis followed by literature review of the clinical presentation and mainstream treatment modalities. GO is a 65-year-old male, with 6-month history of recurrent epigastric pain. He was found to have acute pancreatitis and an adjacent 3.5-cm GDA aneurysm. After conservative treatment of pancreatitis, the aneurysm was treated with coil embolization of the sac and GDA...

Visceral artery revascularisation through a retroperitoneal approach provides an infrequent yet viable, alternative means of managing mesenteric ischaemia in patients with previous abdominal operations. We present a unique case implementing this surgical approach in a 55-year-old man in which we performed a retroperitoneal aortobifemoral bypass with concomitant retrograde jump graft from the aortic prosthesis to the superior mesenteric artery (SMA) for bilateral lower extremity rest pain and chronic mesenteric ischaemia...

Abdominal pain is associated with many gastrointestinal dysfunctions, such as irritable bowel syndrome (IBS), functional dyspepsia, and inflammatory bowel disease (IBD). Visceral hypersensitivity is a key reason for development of abdominal pain that presents in these gastrointestinal disorders/diseases. The pathogenesis of visceral hypersensitivity is complex and still far from being fully understood. In animal studies, visceral hypersensitivity has been linked to several early-life adverse (ELA) events. In humans, IBD, functional dyspepsia, and IBS can have adult onset, though the adverse events that lead to visceral hypersensitivity are largely uncharacterized...

AIM: Patients with long-standing diabetes often demonstrate intestinal dysfunction, characterized as constipation or colonic hypersensitivity. Our previous studies have demonstrated the roles of voltage-gated sodium channels NaV1.7 and NaV1.8 in dorsal root ganglion (DRG) in colonic hypersensitivity of rats with diabetes. This study was designed to determine roles of antioxidant α-lipoic acid (ALA) on sodium channel activities and colonic hypersensitivity of rats with diabetes. METHODS: Streptozotocin was used to induce diabetes in adult female rats...

Visceral artery aneurysm (VAA) is very rare among vascular pathologies. Incidence reported in autopsy series and angiographic studies varies between 0.1% and 0.2%. Most cases are asymptomatic and are diagnosed as result of complications, or incidentally, when imaging is performed for another reason. Three percent of VAAs are superior mesenteric artery (SMA) terminal branch aneurysms. Intra- and/or extraperitoneal bleeding due to ruptured aneurysm is life-threatening condition and requires emergent intervention...

Our recent findings have demonstrated that rodent models of closed head traumatic brain injury exhibit comprehensive evidence of progressive and enduring orofacial allodynias, a hypersensitive pain response induced by non-painful stimulation. These allodynias, tested using thermal hyperalgesia, correlated with changes in several known pain signaling receptors and molecules along the trigeminal pain pathway, especially in the trigeminal nucleus caudalis. This study focused to extend our previous work to investigate the changes in monoamine neurotransmitter immunoreactivity changes in spinal trigeminal nucleus oralis, pars interpolaris and nucleus tractus solitaries following mild to moderate closed head traumatic brain injury, which are related to tactile allodynia, touch-pressure sensitivity, and visceral pain...

BACKGROUND: Urinary incontinence is a very common and debilitating problem affecting about 50% of women at some point in their lives. Stress urinary incontinence (SUI) is a predominant cause in 30% to 80% of these women imposing significant health and economic burden on society and the women affected. Mid-urethral sling (MUS) operations are a recognised minimally invasive surgical treatment for SUI. MUS involves the passage of a small strip of tape through either the retropubic or obturator space, with entry or exit points at the lower abdomen or groin, respectively...

Activation of the serotonin type 4 (5-HT4) receptors has been reported to improve abdominal pain in patients with functional gastrointestinal disorders and reduce visceral nociception in animal models. Earlier studies have proposed that 5-HT4 agonist can produce visceral analgesia by acting at the supraspinal level, but the underlying neuronal mechanisms remain unclear. The caudal ventrolateral medulla (CVLM) is the first site for processing of visceral nociceptive signals ascending via spinal pathways and an important component of the endogenous pain modulatory system...

Background: Enterochromaffin cells (EC) synthesize and release 5-HT and ATP to trigger or modulate gut neural reflexes and transmit information about visceral/pain sensation. Alterations in 5-HT signaling mechanisms may contribute to the pathogenesis of IBD or IBS, but the pharmacologic or molecular mechanisms modulating Ca(2+)-dependent 5-HT release are not understood. Previous studies indicated that purinergic signaling via ATP and ADP is an important mechanism in modulation of 5-HT release. However, EC cells also respond to UTP and UDP suggesting uridine triphosphate receptor and signaling pathways are involved as well...

BACKGROUND AND PURPOSE: Visceral hypersensitivity is responsible for pathogenesis of irritable bowel syndrome (IBS). Therefore, its prevention can help avoid abdominal pain and discomfort in IBS. To find candidate drugs for visceral hypersensitivity, we screened existing medicines for their ability to prevent visceral sensitivity induced by colorectal distension (CRD) in rats and identified chlorpromazine, a typical antipsychotic drug, as a candidate compound. In this study, we investigated the effect of chlorpromazine on visceral hypersensitivity...

PURPOSE: Symptoms such as nausea, vomiting, tightness of the chest, bradycardia, and shoulder or abdominal discomfort, caused by vagotonia occurring during uterus manipulation, have concerned healthcare professionals for some time. Patients sometimes report these symptoms when undergoing spinal anesthesia for cesarean sections (CSs). We designed a prospective, double-blind study to investigate the effectiveness of tenoxicam in preventing these symptoms of discomfort. METHODS: A total of 105 American Society of Anesthesiologists (ASA) class I-II nulliparous pregnant women, who were scheduled for a CS, were enrolled into this prospective, double-blind study...

Metabotropic glutamate receptor subtype 5 (mGluR5) is a Group I mGlu subfamily of receptors coupled to the inositol trisphosphate/diacylglycerol pathway. Like other mGluR subtypes, mGluR5s contain a phylogenetically conserved, extracellular orthosteric binding site and a more variable allosteric binding site, located on the heptahelical transmembrane domain. The mGluR5 receptor has proved to be a key pharmacological target in conditions affecting the central nervous system (CNS) but its presence outside the CNS underscores its potential role in pathologies affecting peripheral organs such as the gastrointestinal (GI) tract and accessory digestive organs such as the tongue, liver and pancreas...

Visceral hypersensitivity and abnormal coping are common in children with functional abdominal pain disorders (FAPDs). Thus, it would be expected that children with visceral hypersensitivity would report more pain if their gut is acutely inflamed. The aim of the study was to compare clinical symptoms and somatization of children with and without FAPDs at time of an episode of acute gastroenteritis. Seventy children with acute gastroenteritis and their parents completed the Rome III Diagnostic Questionnaire for Pediatric Functional GI Disorders and the Children's Somatization Inventory...
